Quote:a) what do you think of having a UART on FRAM71 ? does it make any sense at all?

RS-232 has been a great workhorse for 50 years, and is still used in industrial settings for its longer range (hundreds of feet is not uncommon), easier troubleshooting and making things work on the workbench, and the ease of making up custom cables. However, I wonder how many 71B owners who have a use for it already have the HP82169A or FSI169A HPIL-to-RS232 interface adapters. I have the latter, which has two RS-232 ports, and optionally allowed up to 8. There may be some potential customers interested who for various reasons did not get one of these back when they were available, and having the port on the 71 would be nice for them. I take it however that the line drivers and receivers would have to be external. Is that correct? It would still have value.
